Abstract

1. Process for the treatment of solid and meltable tritiated waste, characterized in that it comprises the following stages of melting the waste (14) within an enclosure (6), a hydrogen flow being passed into the molten waste mass (14), thus bringing about a hydrogen bubbling into the molten waste mass, and the hydrogen and gases absorbed in the waste mass are constantly extracted from the enclosure and subjecting the extracted gases to a detritiation treatment consisting of bringing these gases into contact with an oxidation catalyst in order to transform the hydrogen into water vapour and trap said water vapour on a molecular sieve.
